CHARGING PROCEDURE
1. Plug the charger into an appropriate outlet before inserting the battery pack.
2. Insert the battery pack into the charger (
figure B
).
Be sure the pack is fully
seated in the charger.
While charging, the red (charging) LED will flash continuously
(slowly) indicating that the charging process has started.
3. The completion of charge is indicated by the red LED becoming solid. (approximately 5-
6 hours) The pack is fully charged and may be used at this time or left on the charger.
4.
Recharge discharged batteries as soon as possible after use or battery life may
be greatly diminished.
CHARGE INDICATORS
Replace Pack:
These chargers are designed to detect certain problems that can arise with battery packs
which would be indicated by the
red light flashing at a fast rate.
If this occurs, re-insert
battery pack. If problem persists, try a different battery pack to determine if the charger is OK.
If the new pack charges correctly, then the original pack is defective and should be returned
to a service center for recycling. If the new battery pack gives the same trouble indication as
the original, have charger tested at an authorized service center. Note: It may take as long as
fifteen minutes for the charger to determine that the pack is defective.
If the battery pack is too hot or too cold, the LED will alternately blink fast and slow, one flash
at each speed and repeat.
DAISY CHAIN (FIGURE C)
Single and dual port chargers can be electrically connected in any order up to a
maximum of 4 chargers. Each charger has a power-in cord (which plugs into the
electrical outlet) and a power-out cord (which plugs into the next charger).
To connect chargers in a daisy chain:
1.) Plug the power-in cord into an electrical outlet.
2.) Remove the power-in cord from the next charger and plug in the power-out cord from
the charger that is now plugged into the outlet.
3.) Repeat this process for the remaining chargers.
Chargers that are daisy chained together operate independently as though each one was
plugged into a sperate outlet therefore a battery can be removed from anywhere along
the daisy chain without affecting the other chargers.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected indefinitely with the LED illuminated. You
may see the LED return to flashing (charging) state, as the charger will occasionally “top off “
the battery charge.
IMPORTANT CHARGING NOTES
1. Longest life and best performance can be obtained if the battery pack is charged when
the air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery
pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is
important and will prevent serious damage to the battery pack.
Note: The charger will not charge a battery pack if the pack temperature is below
approximately 32°F (0°C) or above 122°F (50°C). The battery pack should be left
in the charger and the charger will begin to charge automatically when the cell
temperature warms up or cools down.
2. The charger and battery pack may become warm to touch while charging. This is a
normal condition, and does not indicate a problem. To facilitate the cooling of the
battery pack after use, avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance
b. Check to see if receptacle is connected to a light switch which turns power off when
you turn out the lights.
c. Move charger and battery pack to a location where the surrounding air temperature
is approximately 65°F - 75°F (18°- 24°C).
d. If charging problems persist, take the tool, battery pack and charger to your local
service center.
4. The battery pack should be recharged when it fails to produce sufficient power on jobs
which were easily done previously. DO NOT CONTINUE to use under these conditions.
Follow the charging procedure. You may also charge a partially used pack whenever you
desire with no adverse affect on the battery pack.
